I have a 2000 Z71. Is it normal for the rear differential to lock occasionally when going around corners? I have read several of the posts regarding the rear differential, but non indicated if it was normal for it to occasionally lock around corners. It was recommended I put in the additive. I did that and no help. Then was told the additive was bad for the rear-end, so I drained and replaced the fluid. No help. Most recently I took off the back plate cleaned all the gears I could. There were no metal shavings on the magnet and no teeth missing on the gears. Replaced the fluid again, and it will still lock occasionally when making turns. Is the occasional locking something that is normal? It is not locked all the time.
